Earth's Magnetic Field is Changing

EARTH'S MAGNETIC FIELD IS CHANGING:

A new study by the European Space Agency's constellation of Swarm satellites reveals that changes may be happening even faster than previously thought. In this map, blue depicts where Earth's magnetic field is weak and red shows regions where it is strong:

Data from Swarm, combined with observations from the CHAMP and Ørsted satellites, show clearly that the field has weakened by about 3.5% at high latitudes over North America, while it has strengthened about 2% over Asia. The region where the field is at its weakest – the South Atlantic Anomaly – has moved steadily westward and weakened further by about 2%. These changes have occured over the relatively brief period between 1999 and mid-2016.

Earth's magnetic field protects us from solar storms and cosmic rays
. Less magnetism means more radiation can penetrate our planet's atmosphere. Indeed, high altitude balloons launched by Spaceweather.com routinely detect increasing levels of cosmic rays over California. Perhaps the ebbing magnetic field over North America contributes to that trend.

Lord Jesus Christ, have mercy on me a sinner.

I don't see an image of the earth and the file -- although I think it is a very interesting article either way.

I don't see the chart either. But it's consoling to know that even our trusty Admin has trouble once in a long time in posting images !

Thank you, Luke.

I corrected the link. Now if you scroll down, you will see the earth's magnetic field.

Yes, and unfortunately, the image was too large to post here, so all I could do is give the link to the entire page at spaceweather.
